STABILITRAK OFF
If your vehicle has StabiliTrak, this message displays
when you turn off StabiliTrak, or when the stability
control has been automatically disabled. To limit wheel
spin and realize the full benefits of the stability
enhancement system, you should normally leave
StabiliTrak on. However, you should turn StabiliTrak off
if your vehicle gets stuck in sand, mud, ice, or snow
and you want to rock your vehicle to attempt to free it,
or if you are driving in extreme off-road conditions
and require more wheel spin. See If Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow on page 4-17. To turn
the StabiliTrak system on or off, see StabiliTrak
®
System on page 4-6.
There are several conditions that can cause this
message to appear.
• One condition is overheating, which could occur if
StabiliTrak activates continuously for an extended
period of time.
• The message also displays if the brake system
warning light is on. See Brake System Warning
Light on page 3-31.
• The message could display if the stability system
takes longer than usual to complete its diagnostic
checks due to driving conditions.
• The message displays if an engine or vehicle
related problem has been detected and the vehicle
needs service. See your dealer/retailer.
• The message also displays if the vehicle is shifted
into 4LO.
The message turns off as soon as the conditions that
caused the message to be displayed are no longer
present.
